Specification of Letters Patent. P t t 391,1; 14,, 192

Application filed December 12, 1918, Serial No. 266,469. Renewed April10, 1920. Serial No. 373,016.

To all whom it may concern Be it known that I, JOHN E. HULTBERG, acitizen of the United States, residing at 127 Pa. Ave. west, l/Varren,in the county of Warren and State of Pennsylvania, have invented certainnew and useful Improvements in Tool-Handles; and I do declare thefollowing to be a full, clear, and exact de scription of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to improvements in tool handles and moreparticularly to those of the type known as bit drivers, in which thehandle is provided with a usually tapered socket receiving thecorrespondingly tapered butt of the bit, which hit may be in the form ofa screw driver, chisel, drill, etc. It has been the common practice toemploy a slot in the socket and a wedge for reception in the slot toremove the bit from the socket, but this arrangement is more or lessundesirable, due to the liability of misplacing the wedge. Attempts havebeen made to provide other ejecting means for the bit, but for numerousreasons they have proven ineffective or undesirable. It is the object ofmy invention to provide a simple and inexpensive device confined totallyin the tool handle for removing the bit when required, novel provisionbeing made for holding the ejecting device against operationwhile thetool is in use, but for permitting actuation of such ejecting devicewhen necessary. To this end the invention resides in the novel featuresof construction hereinafter fully described and claimed. Figure 1 of theaccompanying drawings is a side elevation of a bit driver constructed inaccordance with my invention. Fig. 2 is a central longitudinal section.

Figs. 3 and 4: are transverse sections on the planes of the lines 3-3and 44: respectively of Fig. 2.

Fig. 5 is a perspective view of the bit ejector and the means fornormally holding it against operation. 7

In the drawing above briefly described, the numeral 1 designates ahandle ofwood or other preferred material, said handle having on itsfront end a ferrule 2 which carries a bit socket 3, the bit receivingrecess 4 of said socket being tapered for snug engagement with the butt5 of the bit 6. The exterior of the socket 3 is preferably pro videdwith flat surfaces 7 so that a wrench efficient and in every waydesirable. though, the details shown and described are front end of saidopening receiving said lug to prevent relative turning of the bit andhandle.

The handle 1 is provided with a central longitudinal bore 10 openingthrough both of its ends and receiving a bit ejecting rod 11. The rod 11is provided at its ifront end with a fiat head which is slidably andnon-rotatably received in the rear end of the opening 8, while the rearend of said rod extends from the handle and hasv threaded thereon a nutor cap 13. When this nut or cap is tightened, the head 12 is held incontact with the front end of the I handle 1 and out of contact with thebit lug 9, but when said nut or cap is loosened as in Fig. 2 and rappedwith a hammer or' the like, the rod 11 will so shift as to cause head 12to strike the aforesaid lug 9, thereby driving the bit from the socket.Whenever-required, removal of the nut or cap 13, will permit withdrawalof the entire rod 11 through the recess 4.

By constructing the device as or substantially as shown and described,it will not only be simple and inexpensive, but highly preferablyfollowed, it is to be understood that within the scope of the inventionas claimed, considerable latitude is allowed for making numerous minorchanges.

I claim:

1. In a bit driver a handle having a bit 7 receiving socket at its frontend, a bit-ejecting rod slidable in said handle, said rod beingrearwardly movable out of contact with the bit, means for preventingrotation of said rod and for limiting the rearward movement thereof, anda cap threaded on the rear end of said rod for contact with the rear endof said handle, to normally hold the rod at its limit of rearwardmovement and out of contact with the bit.

2. In a bit driver,'a handle provided with a central longitudinal bore,a socket member secured on the front end of said handle and provided inits front end with a bit receivin recess, said socket member having aflat-sic ed opening leading to the handle from said recess; the frontend of said opening being adapted to receive the usual fiat lug onthebit butt, a bit-ejecting rod slid able in said bore and having a flathead occupying'the rear end 01 said opening, said head being movablerearwardly against the front end of said handle to'norm ally by saidhead.

In testimony whereof I have hereunto set my hand.

JOHN E. HULTBERGL
